我对编码非常陌生，我正在尝试通过我的新网页弄清楚几件事。我为Navbar使用了引导模板。我删除了它附带的一些链接，并根据自己的喜好对其进行了自定义。我的问题是，当我将浏览器缩小到移动大小时，会出现右侧的切换，但是单击时什么也没发生。同样，当浏览器缩小到移动大小时，导航栏上的列表项将被推到左侧，并向下堆叠。就像我说的那样，我对编码非常陌生，并且我自己学习。这是我的代码。
<style>
.navbar-brand {
padding-right: 70px;
padding-left: 0px;
}
.navbar-inverse {
height: 75px;
margin-bottom: 0px;
}
.nav li {
padding-right: 30px;
padding-top: 10px;
font-size: 1.1em;
font-weight: 700;
}
</style>
<nav class="navbar navbar-inverse">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a></li>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class= id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li><a href="#">Home</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Rates</a></li>
<li><a href="#">Locations</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
最佳答案
这意味着您没有包含jQuery库，或者没有正确放置它。您可以visit this link for the basic template，并且如您所见，在jQuery / bootstrap.js之前，bootstrap.min.js首先包括在内。这部分<div class= id="bs-example-navbar-collapse-1">应该是<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">，请注意，类collapse和navbar-collapse有助于导航栏折叠。
您可以尝试以下操作：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
